Railroad-crossing.



i 'To all wi'io'm it concern `Beit known that'I, ISAAC Li -ARN Crossings, 'of 'which the following is a specification.

My invention relates to improvements in 'railroad crossings;

The object of my invention is to eliminate the noise and Jolting caused by' ear wheels crossing intersecting tracks.``

My invention relates to the type of track crossings in whichI the rails at the intersecting points are grooved in their upper sides to permit the passage of the flanges of wheels running on the intersecting rails.

y invention provides a support for the wheels so disposed that as the wheels cross the grooves in the rails the wheels will be elevated and their treads removed from contact with the rails on which they are traveling. Preferably the wheel support.v is disposed so as to support the flanges of the wheels at the time the wheels are crossing the. grooves.

The novel features of my invention are lwreinafter'fully described and claimed.

in the accompanying drau-'ingsillustrative of my invention, Figure l is a plan view of my improved crossing plate which emboflies the preferred form of'iny invention. Fig. 2 1s a side elevation of. the crossing plate showing car wheels supported thereon,

Fig. if is a cross Section on the dotted linev a-i of Fig. 2. Fig. 4 is a. longitudinal section on the dotted line .ff-ol of Fig. l.

Similar reference characters denote similar parts.

l denotes a horizontal plate on the upper side ot' which are provided the rails 2 and :l ol' two crossed tracks, said rails being integral with the plate 1 or separate parts attached thereto as may he preferred. The upper side. of cach rail 2 and 3 i:: provided at the intersecting points with transverse grooves 4 located at. the inner sides of the cross-ing rails for receiving the flanges of the wia-els running on the crossingl rails.

denotes the. car wheels and (l and 7 the flanges and treads thereof. Atthe rall- 111-' ters( 'ions are provided supports by'which the heels .i are elevated as they cross the grooves 4 so that. their treads 7 do not have y tjslieciaeatioakiriettersraient. appnca'tio'n alednarn 15, 1910. serialNo. Massai l ART,

"contact'with the rails at opposite of the gro'oves'ltl :The jar'and noise: usually produced by wheels c'rossin the grooves in' the rails are thus eliminate Preferablyfas a means for so elvatingthe wheels, 'I provide raised supports 8'Which may be integral with 'or 'separate from'the plate 11.- `The supports 8 are preferably disposed at the intersections of the grooves t respectively andatthe inner sides of the railsQL and 3; The heightl ofsuch'supports 8 is such that as thekfwh'eels are crossing the grooves 4' the wheelswill be supported"byl their flanges 6 on the supports 8. Preferably the upper sides of the supports 8 are belowthe level of the tops of the rails 2 and 3, so `that-the rails may serve to preventV lateral movement of the wheels. As shoe-'nin the drawings, the supports S-at opposite sides of the grooves 4 incline downwardly from said grooves so that the flanges will gradually ride onto and ott of the supports as the Wheels approach and recede from the grooves 4. The usual flange guards 9 may be provided on the plate l intermediate of the rails of each track.

In the operation of my invention, the wheel approaching a rail intersection will first have its flange run upon the adjacent inclined end of the adjacent support 8. When the wheel reaches the adjacent groove 4 the tread 7 will be out of contact with the rail and the flange (i will support- 'the wheel. .\s the wheel travels along the flange (i will run down the oppositely inclined part of the support S until the tread (3 again' rests upon the rail.` fn practice the inclination of the ends of the supports 8 may be as gradual or as abrupt as desired, and the height ot' the supports 8 may be also as desired, it being of course understood that; the height'. may be just. suflicient to prevent the tread ot' the wheel striking the rail at opposite edges ot' the groove. lt is also desirable to have-relatively long inclined por- (ions of the supports so that the wheelsl will be gradually sliiit'ted from the treads to the flanges.

f donot limit my invention to the specific structure. shown and described, as it is obvious thatl many modifications of my invention, within the scope of the appended clain'is, may be made without departing from its spirit.

Having thus described my invention,

what I claim anddesire to secure by Letters.

Patent, is n l 1.A rail road track crossing having two crossed rails, each at the point Ofintersection having a transverse groove in its upper side to receive the flanges of wheels running on the other rail, and a ange support, the height and disposition of which is such that as the wheels cross said groovesv they will be supported by said supportlon their flanges, said support at opposite sides of.

each of said grooves being downwardly inclined from said groove, whereby the weight will be gradually shifted'A from the treads to the flanges and from the flanges to the treads as the wheels approach and recede respectively from said groovesbthe tread portions of the rails alongside of the ange supports being Vin the saine horizontal' plane as ,the remaining tread portions of the rails.

2. A rail road crossing plate having on its upper side two pairs of 'crossed rails, each rail at ,its `point ofyintersection with another -of the rails having in its ,upper side ,a transverse groove 'to receive the flanges of wheels running von a crossing rail, and supports for the lflanges of thefwheels located respectively at thedierent groove intersections and having a height and dis posit-ion suchthat as the vwheels cross the grooves they will .be supported by said sup- 'ports on their flanges, each of said supports at opposite sides of the adjacent groove inclining downwardly from the groove, whereby the weight will be gradually shifted from the treads to the flanges and'from the l ianges to the treads as the wheels-approach subscribing Witnesses.
